Sadly, not.  I know this is an ordering issue.  What I
don't know __where__ the issue comes from as the MSVC
error output doesn't mention any line numbers in pdbsingle.cpp.

I'm also unable to find where (all) the windows headers
define CALLBACK.  A (case insensitive) google search
finds a lot of unrelated chatter about callback functions.
The mingw headers define CALLBACK in a half dozen different
headers.

I'm hoping that someone with in interest in building pva2pva
on Windows will step up to help straighten this out.
